RF Tag with Memory Management

1. A system, comprising: a radio frequency (RF) tag comprising a controller, a memory, and a memory manager, wherein the controller utilizes the memory manager to manage different memory types as part of the memory, the memory types comprising a plurality of one-time programmable (OTP) non-volatile memory locations and a plurality of multiple-time programmable (MTP) memory locations for storing data, and a plurality of OTP memory locations configured as an emulated MTP (eMTP) memory location to emulate a hardened memory, wherein the RF tag is at least in part powered by an external RF signal received by the RF tag.

2. The system of claim 1 , wherein the memory is partitioned into a plurality of functional areas comprising a public and private functional area.

3. The system of claim 2 , wherein the private functional area of memory is encrypted.

4. The system of claim 2 , wherein the private functional area of memory requires an authentication verification to gain access.

5. The system of claim 2 , wherein the plurality of functional areas comprises a volatile and non-volatile functional area.

6. The system of claim 1 , wherein the memory manager is adapted to utilize MTP memory locations to store address information for data stored in OTP memory.

7. The system of claim 6 , wherein at least a first of the plurality of MTP memory locations stores redundant data with at least a second of the plurality of MTP memory locations.

8. The system of claim 1 , wherein the OTP non-volatile memory locations comprise at least one of fuse and anti-fuse OTP memory.

9. The system of claim 1 , wherein at least one of the MTP memory locations comprise a plurality of OTP non-volatile memory locations configured to resist effects of environmental changes, enabling the at least one MTP memory location to emulate a hardened memory.

10. The system of claim 9 , wherein at least one of the environmental changes is an increase in mechanical vibration.

11. The system of claim 9 , wherein at least one of the environmental changes is a change in temperature.

12. The system of claim 9 , wherein at least one of the environmental changes is a change in humidity.

13. The system of claim 9 , wherein at least one of the environmental changes is an increase in ionizing radiation.

14. The system of claim 13 , wherein the ionizing radiation is an exposure level greater than 25 kGy.

15. The system of claim 9 , wherein at least one of the environmental change is mechanical shock.

16. The system of claim 1 , wherein at least a subset of the plurality of OTP memory locations are arranged in a manner that allows the RF tag to have a memory store that withstands radiation exposure.

17. The system of claim 1 , wherein the OTP non-volatile memory locations are operable through an exposure of the RF tag to ionizing radiation exposure.

18. A method, comprising: providing a radio frequency (RF) tag comprising a controller, a memory, and a memory manager, wherein the controller utilizes the memory manager to manage different memory types as part of the memory, the memory types comprising a plurality of one-time programmable (OTP) non-volatile memory locations and a plurality of multiple-time programmable (MTP) memory locations for storing data, and a plurality of OTP memory locations configured as an emulated MTP (eMTP) memory location to emulate a hardened memory, wherein the RF tag is at least in part powered by an external RF signal received by the RF tag.
